In collaboration with the organizers of Earth Hour 2016, the global environmental event that will take place next Saturday at 8.30 pm your local time, we are happy to announce a special edition of the Climate Challenge. www.ecoresearch.net/climate-challenge

Earth Hour 2016 comes at a moment when the world stands at a climate crossroads. We are emerging from a year that saw us both celebrate a universal climate deal and learn that our planet had lived through the hottest year on record. Shining a light on the climate action has never been more important or urgent.
